March 2001 - ENERGYguide.com announced an agreement with Sterling Planet, Inc. to offer a 100% green electricity product to residential and business customers across the continental United States. Sterling Planet is an Internet-based green power marketer based in Roswell, Georgia.

The companies are offering consumers an option to purchase green power equivalent to 50%, 75% or 100% of their power consumption at an additional cost of 10-20% of their monthly electricity bill, or about $10-15 more per month. Sterling Planet promises to use the revenues to add renewable electricity to the national electric grid to "replace an equal amount of conventional electricity" as demanded by consumers. According to the company, the green power will come from renewable sources such as wind, solar, small hydro, geothermal, and biomass.

Consumers are not required to switch suppliers to participate in the program and will continue to receive a monthly bill from their current electricity supplier. According to Sterling Planet, there are no long-term contracts, and buyers can increase, decrease or cancel their green purchases at any time. The company claims that it will "partner with utilities" to offer the green power choice.
